Title: Improvements in or relating to the manufacture of multistrand steel ropes or cables
Inventor: QUERALTO MARTIN TRUJOLS
IPC: D07B7/00
Filed: 1968-09-20
Abstract: 1,242,244. Treating multi-strand steel cable. M. T. QUERALTO. 20 Sept., 1968 [23 Sept., 1967], No. 44892/68. Heading D1T. A method of treating multi-strand steel cable comprises freely passing the cable through a heat treatment zone under a tension sufficient to produce a permanent stretching of the cable. In Fig. 1 the cable 3 passes freely through a heating zone 6 whilst under tension, this tension being set up by a winding drum 5 pulling the cable over a plurality of rollers 2 causing the cable to follow a predetermined sinuous path. The setting of the rollers 2 is adjustable by means of devices 4. The cable may pass through a cooling zone 7. The tension may be between 55 and 85 per cent. of the breaking load of the cable. It has been found that:-1, The elastic limit of the cable is increased; 2, The elongation or stretching of the cable before it breaks also increases; 3, The initial stretching with small loads is reduced since the wires are in contact with each other; 4, The cable is straightened, facilitating its laying in sheaths; 5, The wires forming the cable fit each other.

Title: Drive mechanism for the plunger of a plunger-and-die type folding box machine
IPC: B31B50/44
Filed: 1962-11-28
Abstract: 975,796. Converting rotary into reciprocating motion; cam mechanisms. ATLAS GENERAL INDUSTRIES Inc. Nov. 28, 1962 [Dec. 1, 1961], No. 44929/62. Headings F2K and F2Q. [Also in Division B5] In a plunger and die type box-making machine for folding a blank into shape or for inserting a liner in a box, wherein a plunger such as 123, Fig. 5, is carried by a crosshead bar 11 which is reciprocated on a guide column 13, Fig. 4, by a crank linkage, Fig. 1 (not shown), the reciprocating crosshead bar 11 carries a shaft 36 which is oscillated during the reciprocation by an arm 40 thereon having a roller engaging a fixed 8-shaped cam track 42. The oscillating shaft 36 carries an arm 39 which may be used, as is the arm 139 in Fig. 5, to give an increased length of stroke to the plunger 123. Alternatively, in a machine of the type wherein the crosshead bar 11, Fig. 2, reciprocates a main plunger 24 carrying on a spring- retracted stem 28 a separate ejecting plunger 27 for inserting a liner in a box, the stem 28 may be actuated by the arm 39, thus dispensing with the normal impact-actuated lever 35. The cam track 42, Fig. 4, comprises a fixed portion 43 and a portion 45 pivotally mounted at its upper or lower end and biased at the other end by a spring 47, the portion 45 coacting with a switch 48 which operates a signal, or stops the machine, should the full stroke of the plungers be resisted (e.g. by the presence of an extra lining). The yielding cam portion 45 thus prevents damage to the machine.

Title: Method and apparatus for continuously casting hollow rounds
IPC: B22D11/08
Filed: 1971-09-28
Abstract: 1367771 Continuous casting USS ENGINEERS & CONSULTANTS Inc 28 Sept 1971 [2 Oct 1970] 45195/71 Heading B3F [Also in Division G3] The inner shell I of a solidifying tubular continuous casting C is directed to keep coaxial with the outer shell E by riding over a body 68 of magnetic material (mild steel) located between the mould 49 and the position where the casting solidifies throughout its wall, because of cooling (by sprays 20, 67) of the shells E and I; the body 68 is maintained coaxial with the shell E by magnetic devices 71, 71a which respond to displacement of the body 68 by exerting magnetic forces on the body for restoring it to coaxial position. The mould is a replaceable copper sleeve 49 mounted in a water-jacket, with partitions 50 and baffles 52 and supported on oscillated beams 14. A replaceable copper mandrel sleeve 55 in the mould 49 is mounted on a water-conveying lance 12 suspended from a ball joint 15 carried by oscillated beams 16. Water from an inlet 59 enters an outer tube 56 of the lance to pass down into the mandrel sleeve 55 and a middle sleeve 57 of the lance. From a top inlet 61, water passes into an inner sleeve 58 of the lance 12 and down through a ball joint 65 at the lance bottom by the mould outlet. A tubular exten sion 64 of the lance is suspended from the joint 65 and bears the magnetic body 68 and a set of nozzles 67, both of which receive the water. Around the casting C and magnetic body 68 are mounted two pairs of positioning magnets of which one pair 71, 71a appears in Fig. 1. If the inner shell I displaces the body 68, an electrical circuit including one pair 73, 73a or other of detecting magnets above the positioning magnets 71, 71a, is put out of resonance and a differential is created between the opposed forces of a pair of the positioning magnets so that this latter pair cause the body 68 to move back to coaxial position to restore the inner shell correspondingly and re-establish circuit nearresonance. Instead of the poles of a magnet being in the same horizontal plane, they may be in a vertical plane. Two more magnetic bodies (69, 70) like body 68 are mounted on a lower section of the lance extension 64 below a ball joint (66) connecting the two sections. The lowest magnetic body lies just above the position where the casting is solidified throughout. The lance 12 passes between the limbs of a U-shaped tundish 21 which feeds molten metal M by way of sliding gates 25 and troughs 22 into the mould cavity 13 initially plugged by an annular head 27, Fig. 4, of a tubular starter bar 26. Slots 35 coact by a bayonet action with bolts 29 in the head to join the parts 26, 27 releasably before plugging the mould. A stand (37), Fig. 2 (not shown), below guide rolls beneath the lowest magnetic body [70), raises the starter bar (26) before casting and afterwards lowers it by means of rolls (38) until it can be gripped by arms (45) for rotational release from the head (27). The casting (C) advances with the head (27) through bending rolls.

Title: An automatic frequency control system
Inventor: CORNEY JOHN VICTOR JAMES
IPC: H04N5/12
Filed: 1965-11-03
Abstract: 1,145,706. Automatic frequency control; transistor circuits. THORN ELECTRONICS Ltd. 2 Nov., 1966 [3 Nov., 1965], No. 46624/65. Headings H3A and H3T. In an automatic frequency control system in which an oscillator is compared with a reference signal to produce an output at point X which is fed through a filter R1, R2, C2 to control the oscillator frequency, an amplifier is connected in parallel with the filter to reduce the time constant of the filter circuit when slip occurs between the two frequencies. The amplifier comprises transistors VT1 . . . VT4. When the two signals are at the same frequency, the base collector junctions of transistors VT1, VT2 are forward biased holding their emitters to near base potential so that these transistors and the two following transistors VT3, VT4 are cut-off. Under this condition the output from the phase comparator 4 is fed via the low pass filter R1, R2, C2 to control the frequency of the oscillator 1 so as to correct the phase difference. When slip occurs, an A.C. output at the slip frequency is produced by the phase comparator and this results in the capacitors C3, C4 charging until the collectors, of VT1, VT2 are at about 0 volts and - V volts respectively. Under these conditions the transistors all become conductive and the signal is fed from point X to point Y via the amplifier, thus reducing the effective time constant of the filter. The R circuit is applied to a television line synchronization system in which a circuit 3 produces trapezoidal pulses from the oscillator output, and circuit 5 produces sampling pulses from the reference signal.

Title: Giant Pulse Laser
Inventor: SOOY WALTER RICHARD
IPC: H01S3/11
Filed: 1967-10-13
Abstract: 1,150,973. Lasers. HUGHES AIRCRAFT CO. 13 Oct., 1967 [19 Oct., 1966], No. 46742/67. Heading H1C. A giant pulse laser includes in the optical cavity an intracavity loss modulator and a Q-switch. In the embodiment of Fig. 1 a pink ruby, neodymium glass or gaseous active medium 17 is positioned in the optical cavity 15 together with a Q-switch 23 comprising a Wollaston or Rochon prism 25 and Kerr or Pockels cell 27, and a bleachable cell 33. In operation a half-wave voltage is applied to the cell 27 so that the regenerative light path is deflected along path 21 so as to strike mirror 11 at right angles and form a regenerative path and the laser 17 is pumped by pumping source 19. Very little or no oscillation occurs at first due to the bleachable cell 33 until a certain energy level is reached when the light cell 33 becomes transparent and laser energy is allowed to travel along the regenerative path 21. Once oscillations take place bleachable cell 33 operates as a self-mode locked intracavity loss modulator to introduce a loss term oscillating at the intermode spacing, and the small amount of energy 35 passing through mirror 13 will be in the form of a series of sharp (sub nano-second) spikes of increasing amplitude. When these pulses reach their maximum amplitude photodiode 37 passes a signal via line 41 sufficient to fire thyratron 29 and so short the supply to electro-optic cell 27. This results in the light path 21 being deflected to path 31 such that the reflected light energy from mirror 11 passes out of the cavity in the form of a single spike output and the laser action terminates. The Passive Q-switch bleachable cell 33 may function mainly as a Q-switch in which case a separate intracavity loss modulator such as an R.F. driven quartz transducer may be positioned between the active medium 17 and mirror 13, Fig. 3 (not shown). In the embodiment of Fig. 4 the passive Q-switch is replaced by an active Q-switch utilizing the polarization properties of the laser active medium which Q-switch comprises an electro-optical cell 81. A trigger signal from source 85 is coupled both to the pumping power supply 83 and to delay line 87 which has a delay of sufficient length to allow ruby element 17A to reach its high population inversion before the trigger signal fires thyratron 91 thereby interrupting the electric field in cell 81 to allow regeneration in the cavity 15 to begin. A separate loss modulator 71 is used in this embodiment. The photodiode 37 of Fig. 4 may be replaced by timed system, Fig. 5 (not shown), in which the control grid of thyratron 29 is connected via a delay line to the output of delay line 87.
